Write the next chapter of a 40-year story
As Business Development Manager atMAC Ltd, you’re backed by 40 years of world-leading expertise — and trusted tobuild the future.
Since 1986we’ve been solving the hardest problems in wireless communications. Founded byProfessor Raymond Steele — one of the founding fathers of modern mobilecommunications — we’ve worked on every generation of mobile technology, fromearly analogue to 5G. Today we apply world-leading expertise in advanced signalprocessing and software defined radio to difficult challenges in defence,security and space.
Following our2025 move to employee ownership, we’re ambitious for what comes next. We’relooking for a Business Development Manager (BDM) to work closely with theManaging Director and leadership team, identifying the markets and customerswhere our expertise can add most value, and building the commercial engine to drivethe business forward.
A different kind of sale
We’re notselling a product off the shelf. We sell design services, backed by deeptechnical expertise, to customers who often need help to articulate what theyneed. They know they have a challenge somewhere in the radio andelectromagnetic spectrum domain, but the shape of the solution, and its value,emerges by working it through together.
That means thesale is based on discovery. Sitting with a customer, asking the rightquestions, understanding their world, and helping them see what’s possible —that’s the heart of this job. If that’s the kind of selling you find mostrewarding, this role is perfect for you.
Why this role is different
You’ll focuson solving real problems. The best moments in this role happen in the roomwith a customer, when a vague concern turns into a clearly understood problemMAC Ltd can solve. You’ll have world-class engineers alongside you to go deepwhen needed — but you’re the one who creates those conversations and knows howto draw the real requirement out.
You havecomplete confidence in what you’re selling. When you tell a customer MAC Ltdwill solve their problem, you’ll be describing what has actually happened, forforty years, for some of the most demanding customers in defence, security andspace. No over-promising. No hoping delivery catches up. Your reputation andours are completely aligned.
You’ll shapethe next phase of MAC Ltd’s journey. You’ll work directly with Pete, ourManaging Director (MD), and the senior leadership team — engineers who trainedunder Professor Steele and now own the business through our Employee OwnershipTrust. You’ll report to the MD, present to the Board, and have a genuine voicein our strategic direction and growth plan. This is a seat at the table, not asales desk in the corner.
You’ll shapethe commercial engine. There are foundations in place — but the BDM role isearly in its development, and you’ll play the leading role in how it grows.Working closely with the Managing Director, you’ll shape the client engagementapproach, the pipeline discipline, the industry relationships and MAC Ltd’spresence at trade events.
